Introduction to Enterprise JavaBeans (EJBs)
Sun Microsystems's JavaBeans provide a means of modularizing applications with
simple, reusable components. While they are very useful for local use, JavaBeans
themselves are too simple to add much value to enterprise-level business
applications. Enter Enterprise JavaBeans (EJBs). Though they share part of their
name with standard JavaBeans, EJBs are a whole different animal. With built-in
support for the common infrastructure issues of object persistence, security,
and transaction management, EJBs combine server-side components with distributed
object technology. This results in greatly simplified program development by
allowing developers to spend their time concentrating on the business logic
specific to their applications.
This 5-day hands-on class covers the EJB fundamentals of implementing
session, entity, and the new EJB 2.0 message-driven beans. Students will then
delve into more complex topics like distributed transactional programming,
exception handling, and security and performance issues. The class also presents
invaluable design and testing strategies that have been proven in the field. In
addition, the instructor will often discuss issues of troubleshooting and best
practices as they relate to the various topics presented throughout the workshop.
Students will have the opportunity to utilize their new skills with many
hands-on exercises using Java 2 Software Development Kit (SDK) version 1.4.
Who Should Attend
This workshop is designed for experience Java developers who wish to create
Java 2 Platform, Enterprise Edition, (J2EE) applications using secure, scalable,
and transactional EJB components.
Prerequisites
Students are expected to have a strong Java programming background, with
experience in advanced techniques such as multithreading. Familiarity with JDBC
and transactional programming is helpful, though not necessary. The instructor
will assume, however, that students know the basics of relational databases and
SQL.
Workshop Objectives:
- Understand the roles and architecture of EJBs.
- Implement session, entity, and message-driven beans.
- Compare Bean-Managed and Container-Managed Persistence (BMP and CMP).
- Learn about the services offered by the EJB container and successfully
manage its resources.
- Optimize the performance of your EJB application.
- Use local and distributed transactions to ensure data integrity.
- Design robust, secure, and scalable applications.
- Create a test suite that meets the challenges of the EJB environment.
